To all 'whom it may concern Be it known that I, JOHN H. S'roNEMn'rz, a citizen of the United States, and a resident of Grand Haven, in the County of Ottawa and State of Michigan, have invented certain new and useful Improvements in Paper-Cutting Machines, of which the followingis a full, clear, and exact specification.

This invention relates to paper cutting machines in which a number of layers of paper or card board laid upona bed plate are simultaneously severed to size, or trimmed as may be, by a reciprocating knife blade, actuated by means of power or hand operative mechanism.

The prime object of this invention is a paper cutting machine of the character above referred to, in which the number and simplicity of parts are reduced to a minimum, and access thereto for adjustment, repairs and the substitution for injured parts substantially promoted and made convenient. i

- Another object of this invention is to have a paper cutting machine so constructed that it may be quickly converted to a hand or power operating machine and vice verse. by any ordinary mechanic in the entire absence of cutting, drilling, fitting or machine shop work other than assembling parts previously finished, and thereby reducing the expense of such conversion to a minimum both in cost and time for making the same.

A further object is to have the knife blade so constructed as to provide easy access" thereto for its removal for substitution for sharpening and other purposes.

A. still further object is to have the counterbalance so arranged and connected therewith that the machine may be shifted from a hand to a power mechanism and vice versa, and the knife blade be removed and ram sorted in the absence of the liability of any movement on the part of the knife blade to the injury of the operator making the change.

Another object is to have the tape, indicating the position of the knife gage, automatically operated to take up slack therein, and thereby indicate the relative position of the gage to the knife blade at every point of its adjustment.-

lVith these ends in view, my invention finds embodiment in certain features of novframe.

elty the construction, combination and arrangement of parts by which the said ob ects and certain other. objects are hereinafter attained, all as fully described with reference to the accompanying drawings, and more particularly pointed out in the claims.

said drawings: Figure 1 illustrates av front endelevation of a paper cutting machme embodying my invention. Fig. 2 is an end elevation of the left hand end of the machine. Fig. 3 is an end elevation of the rlght hand end of the machine. Fig. 4. is a vertical section. Fig. 5 is an enlarged detail section of the brake, clutch and pulley mechanism for the power shaft. Fig. 6 is an elevation of the inner side of the clutch and pulley for the power shaft. Fig. 7 is a detail end elevation of the stop collar with a pin passing therethrough into the main Fig. 8 is a detail view, in side elevation, of thebi ake for the power shaft; and, Fig. 9 is a top plan view.

Similar characters of reference indicate the same parts in the several figures of the drawings.

For convenience and clearness of description, the paper cutting machine, containing my invention, will first be described, as constructed, when operated as a power ma chine.

The base 9 is provided with slot-like openings 10 and 11 in each end thereof extending from a line just below the bottom of a longitudinal power shaft 12 projecting through said openings and supported by plates 13 and 14 rigidly secured to the base by cat bolts 15, 16 respectively supporting the boxes 17 and 1-8 forming the-bearings for the power shaft 12, and the sides of the base are also reamed out at 19, 19 for-drive shafts 4:8 and 58*.

Mounted upon this base and secured by suitable bolts 20 is a bed plate 21, forming a support for an arch 22 secured thereto by means of bolts 23, the uprights of the arch' .conveniently cast and require but little finishing.

On the power shaft 12 are respectively fast and loose pulleys 26 and 27,- the pulley 27 being provided (see Fig. 5) with a clutch ring 28 expansible to tighten the. pulley' on the shaft by a cone 29 through its engagement with an expanding device 30, thecone 29 being provided with a circumferential groove 31 engaged by opposing pins 31 projecting inwardly from the bifurcated end of and actuated by a lever 31 fast about centrally of its length to a pintle 33, having its bearing in a hub 31 jecting from the plate 14, to which pintle is also secured a shifting lever 32 by a pin 32 passing through the hub of the lever and the pintle.

Sleeved on the power shaft 12 is a hub 34 of a brake wheel 35 preferably covered with leather and opposed by a brake shoe 36 forming a part of a lever 37 pivoted to a lateral extension of the arm 34 of the plate 14.

The brake lever 37 is provided with an upturned end 39 and is actuated to contact with the brake wheel 35 by a spring 40 hearing against the brake lever and supported in its operative position by a pin 41 passing loosely through a slot 42 in the brake lever, said pin being tapped into the brake hub 34 and provided, at its upper end, with a washer 43 forming a bearing for the upper end of the spring 40, the tension of which may be increased or diminished by means of nuts 44 on the upper end of the pin 41.

When these several parts are in the position shown in Fig. 5, the clutch is out of its operative position not tightening the loose pulley upon the shaft 12 and the brake lever is in engagement with the brake wheel and held in this position by means of an anti-friction roller 45 on the lever 32.

When, however, the lower end of the lever 32 is moved outwardly, the anti-friction roller 45, by its engagement with the upturned end 39 of the brake lever, will force the brake away from the brake wheel against the resistance of its spring about the time the loose pulley is tightened on the shaft 12,

' the operation of the shifting lever 32 being performed by hand, as indicated in Fig. 1.

On the opposite end of the shaft 12 and inwardly of the base structure, is a worm gear 46 in constant engagement with a worm gear 47 on a short drive shaft 48, and on the outer end of the shaft 12 is a clutch crank 49 for operating the power shaft independently of power mechanism, when, for any purpose this may be necessary as hereinafter more specifically referred to.

On the worm gear wheel 47 is a stud 50, provided with a perforation for a spring key 51 for securing a lever 52 thereon, the upper end of said lever projecting (see Figs. 1 and 9) between the grooved or bifurcated arms 53, 53 projecting from a cutter blade on an arm 34 pro-v head 53, by means of a pivot bolt 54, onthe outer projecting end of which is also pivoted a counter-weight lever 55, the lower end of which is connected with a lug 56 by ineans of a pivot 57 projecting from said The lug 56 projects from a hub 58, sleeved on a short shaft 58, and from which depends. an arm 59 suspending a counterweight 60.

The knife head is suspended by means of (see Fig. 1) links 61 and 62, pivoted to the outer ends thereof, and at their upper ends to the arch, with the result that the cutter blade in operation has a swinging movement producing a sheer-like cut through the paper resting upon the bed plate, and, together with its head, is so balanced at every point of its movement that its operating .lever and other actuating devices are re lieved from all strain due to the very consildglrable weight of the cutter head and The cutter head 53 is provided with a recess 63 (see Fig. 4) in which the shank of a cutter blade 64 is seated, the cutter blade being provided at intervals of its length with lugs 65 having elongated slots 66 for the passage of bolts 67 screw-threaded in the head for clamping the cutter blade thereto, the cutter blade 64 being adjusted in its head with reference to the bed plate by means (see Fig. 1) of screw bolts 68 made for the first time accessible from the front of the machine, by means of slots 69, 69 through the cutter head, the heads of such bolts being provided with perforations 70 at intervals whereby the bolts may be conveniently and quickly adjusted by means of a straight pin or even a wire nail, when, as heretofore constructed the bolts were only accessible from the top of the knife head or bar, or by means of a pin wrench from behind, which is not only inconvenient but a and the edge of the knife are in view throughout the adjustment desired to be made.

When installing a cutting blade it is first loosely suspended by its lugs 65 from the bolts 67 with the edge resting by the gravity of the blade upon the opposing surface of the bed plate, then the lever screws 68 are turned until their heads are in contact with the back edge of the blade structure, and after this is done the bolts 67 are tightened and the blade thereby clamped to its head in a position of perfect adjustment relative to the bed plate, so that when it descends through thepaper it will cut through the bottom sheet as perfectly as it will the sheets above the same.

The bed plate 21, toward its rear edge 'front of the machine where the bed plate (see Fig. 4) is provided with a groove 71 'for holding the stick 72 with which the cutting blade contacts on passing through the ,cut paper, andto better sustain the force of the blade the bed plate is thickened at-this bending or sagging'under the force of-the cutter blade. I a

The bed late (see Figs. 1 and 9) is cast with a slot 3, and with an end bar 7 4, upon which is mounted a gage block 76 of the usual sectional constructiom-secured to a slide block 7 7 to which the-central section of the gage block is secured by a screw bolt 78, said block being provided'with internal screw threads 79 engaged by screw threads shaft, at its rear end, is centered upon an adjustable screw 82, working in a lug 83, depending from the end a bar 74, and locked in its adjustment by a through the nut 75. a

' The forward end of the shaft 81 projects wall of the base, and has its bearing in a bracket 84 depending from the bed plate, which bracket also supports a pivot bolt 85 screwed therein, forming the vided with internal gear teeth 87 meshing with a pinion 88 on the end of the shaft 81.

In lockingthe hand wheel-against accidental movement, (see Flg. 1) a bracket 81 is secured by screw threaded bolts 81, 81 to the underside of the bed plate 21, and provided with a thumb screw 81 adapted to be tightened against the periphery of the hand wheel 86. I

As heretofore constructed the actuating shaft of the gage block has been operated by a crank arm attached directly to the end of the shaft, with the result that much time and labor have been lost in adjusting the gage, and particularly from one extreme to the other of its adjustment, and while this has long been an objection I am seemingly the first to employ in a paper cutting machine a pinion and gear by which to provide a means for causing the adjusting screw to make a plurality of revolutions for one revolution of a hand wheel, or, as indicated in the drawings, four revolutions to one complete revolution of a hand wheel actuating it.

The gage block 76 (see Flgs. 4 and 9) is in three sections, 76, 76 and 76, the sections 7 6 and 7 6 being provided with flanges 89, and longitudinal of the central section 76 are slots89 through which slots pass thumb screws 90 screwing into adjacent side flanges 89 of the sections 76 and 76", thereby providing for so adjusting the gage that the cutter bar may simultaneously trim operative wheel 86 pro-.

slot of a lug 92' (see Figs. Land 9) projecting from the slide block '77 through a slot in the section 76.

On the screw threaded bolt 78" at each side of the lug 92 are nuts 92, which, by their adjustment upon the right and left screw threaded bolt 78 are adapted to swing the section 7 6 laterally upon a pivot formed by the bolt 78 until the gage block is in 'or out of alinement', asmay be, the cutter knife, the gage block being secured in its adjustable position by tightening the=nuts 92 aga irst the' lug 92 and the tightening of=the bolt 78.

Mounted upon thegage block section 76 (see Fig.4) is a post.93 rising to about a plane :'th the underside of the top of the arch-'22, which post has secured to its upper -end -a tape, preferably of steel, adjustable by means of a screw threaded pin 95 secured to=the tape and passing through the post 93 to which .it is locked by means of opposing nuts 96, 96, the tape passing thence around a drum 97 pivoted to the underside of thearchand having an internal coiled spring (not shown) automatically winding 'up the tape as the gage block is moved toward the arch.

The gage 94 is preferably provided with gage marks for indicating the proximity of 102 of which is a screw 103 secured to a hub 104: of a hand wheel 105, by means of which the clamp may be raised and lowered after the gage block has been adjusted so that the paper may be held firmly upon the bed plate directing the operation of the cutting knife in severing the paper, the front wall of the clamp affording a bearing surface for the knife and the head 53 to which the blade is secured.

In the operation of my paper cutter as a power machine the normal position of the cutting blade is at the limit of its upward stroke and is caused to move from that potwo studs 113 sition by pushing upon the lever 32 until the clutch on the power shaft 12 expands the clutch ring and tightens the pulley 27 on said shaft which will then revolve as soon as the usual belt (not shown) is shifted from the loose pulley to the clutch pulley by any belt shifter commonly employed for that purpose, but as soon as the cutting blade has returned to the limit of its up stroke the position of the shifting lever 32 is automatically reversed and the clutch thrown out of engagement with the loose pulley by means of a bent lever 106 (see Fig. 1) pivoted to the shifting lever 32, as indicated at 107, above the fulcrum thereof and to a stud 108 on the worm gear 47, with the result that the cutting blade remains in its elevated position until the shifting lever 32 is operated to again move the clutch to its position tightening the pulley 27 on its shaft.

When, for any reason, actuate the cutting blade independently of the power mechanism the clutch crank 49 may be used for that purpose.

Having so far described the embodiment of my invention in a power operating machine, it is important to note, at this point, that the prime object of my invention is to have a paper cutting machine so constructed that they may be operated by hand until a time when it may become necessary to operate it by power, and that when this time arrives it may be quickly converted from a hand to a power operated machine and at a minimum expense.

In other words, when a hand operated machine of my invention is ordered with a view to its possibility of it subsequently being operated by power, as is usually the expectation. all of the necessary machine work upon the base and other parts of the machine for the transformation are completed, and the machine is shipped without being accompanied with the power shaft 12, the pulleys, the worm gear and its shaft, or any of the clutch operating mechanism therefor, but, (see Fig. 3) with a hand operated lever 109 (shown in dotted lines in Fig. 1) secured to the drive shaft 58*, upon which is a crank arm 110 (see Figs. 1 and 3) provided with a removable stud 111 upon which the lever 52 is then secured, with the result that the lower end of the lever 52 is oscillated by the hand lever instead of being continuously revolved as it is when driven by power mechanism from the worm gear 47.

Keyed on the drive shaft 48, when the machine is operated by hand, is (see Fig. 7) a collar 112 from which radially projects and 114 operating to limit the movement of the lever 109 in both directions by alternately engaging a semi-boss 115 formed with and projecting from the machine base. In other words, when the lever it is desirable to is at the limit of its up-stroke, the stud 114 will be in, engagement with the boss, as shown in'Fig. 7, and, accordingly limit the movement of the hand lever in that direction; the engagement of the stud 113 with the boss, when-the lever is swung, will'likewise limit its downward movement.

When the hand lever is at the limit of its upstroke the cutting knife is in its highest position and may be locked in this position against accidental falling to the injury of theoperator when the'machine is not being operated, or when it is desirable to remove the knife for sharpening purposes, and particularly when making the changes necessary to shift the machine from a hand to power operation, in which connection it should be observed that the lever 55, being permanently connected with the crank arm of the counter weight 60, the knife blade is continuously balanced at all times.

The hand lever 109 and the stop collar 112 (see Figs. 1, 2, 7 and 8) are removablysecured to the drive shaft 58 by keys 116 and 117 (see Fig. 1), as a means by which the machine may be converted from a hand to a power machine and vice versa.

. WVhen it is desirable or necessary to change the machine from hand to power operated, the owner need but so notify the manufacturer in general terms when he will be furnished with thepower shaft 12, the several devices mounted and supported thereon, including the bent lever 106, and when received it is only necessary for the installation of these power operating devices to fasten the plates 13 and 14 to their base already tapped to receive the bolts 16 at each end of the machine, insert therein the boxes and the shaft 12 and secure the other devices supported by the shaft in their operating position as shown in Fig. 1, all of which it will be seen may be readily and quickly accomplished in the absence of any shop work other than assembling.

By my invention the cost of construction of a hand operated machine and its subsequent conversion into a power operated machine-is reduced to a minimum, for in casting the base there is no additional cost due to casting the base with end slots through which to project the power shaft, nor for the boss 115 for the drive shaft 48, and substantially no cost for tapping the holes therein for the bolts 10 of the end plates 13 and 14, which slots, boss and screw holes will be the only additions to be made in the base by which to adapt it to a power machine, and without adding substantial cost to the production of a hand operated machine, even though never used for power operating purposes, a machine of my invention, by reason of its convertibility, embodies advantages not only in operation but desirable to a substantial advantage both to the manufacturer and purchaser, and particularly the latter when his business assumes such proportions that a power operated machine is necessary.

These changes are largely due to the employment of the drive shaft 48, providing, as it does, for the support and actuation of the worm gear wheel and a crank arm from one to the other of which may be shifted a lever directl vconnected with and actuating the cutting ife at will either by hand or power, which drive shaft further provides for suspending the counter-balance weight entirely within the base out of sight and out of the way of the operator, and a permanent lever connection between the counter-balance weight and the cutting knife, and in such a manner there is such a constant tendency of the weight to sustain the cutting knife at the limit .of its upward stroke when removing the knife for sharpening and in changing the machine from hand to power operated or vice versa as may be.

Itis proper at thispoint to suggest that when a cutting knife is to be operated by hand power, a lever, and particularly such as the hand lever 109, is best adapted for the application of power to the knife, especiallywhen cutting through a very considerable thickness of paper, and as distinguished from a power machine hand operated by means ofa crank on one end of the power shaft, and which is not the purpose of the clutch crank arm49, its only intended fimction' being that of turning the power shaft to and only to whatever extent may be necessary-for shifting the several parts of the machine from one position to the other i when making repairs, and, to which end, the

crank arm 49 may be thrownout of operationby'simply slipping it off the end of the power shaft 12.
